Resource scheduling method, base station and user equipment

Abstract

Embodiments of the present invention provide a resource scheduling method, a base station, and user equipment. Including: receiving the scheduling request sent by the user equipment UE; determining the scheduling type of the UE, the scheduling type is edge UE or non-edge UE; the base station schedules frequency resources for the UE according to the scheduling type of the UE and the frequency resource configuration of the serving cell of the UE; Send scheduling information to the UE to indicate the frequency resources scheduled by the base station for the UE; frequency resource configuration includes public frequency resources and dedicated frequency resources; virtual multiple-input multiple-output VMIMO pairing is allowed on public frequency resources, which can be used to schedule edge UEs and non- Edge UEs: VMIMO pairing is not allowed on dedicated frequency resources and can only be used to schedule edge UEs. In the embodiment of the present invention, by determining the scheduling type of the UE, the edge UE is preferentially scheduled on the configured dedicated frequency resources, and VMIMO pairing is not performed, so that the throughput and throughput of the edge UE can be improved while ensuring the throughput of the entire VMIMO system. performance.

Description

Technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and more specifically, to a resource scheduling method, base station, and user equipment. Background technique [0002] The Long Term Evolution (LTE) system introduces key technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multi-Input & Multi-Output (MIMO), which significantly increase frequency efficiency and Data transmission rate, system capacity and coverage area have also been significantly improved. [0003] With the increase of LTE users, the demand for system capacity is increasing. Although increasing the system capacity can be achieved by increasing the bandwidth, due to the limited spectrum resources, how to increase the system capacity as much as possible under the limited spectrum resources has become a focus of attention. [0004] The Virtual Multi-Input & Multi-Output (VMIMO) technology in the LTE uplink can pair multiple users, and t...

[0005] However, when VMIMO technology is adopted, the power superposition of paired users will lead to a significant increase in inter-cell interference, and with the increase in the number of paired layers, the number of interference sources will increase, and eventually the interference suppression effect of the receiver will decrease, making the VMIMO system The throughput and performance of the edge user equipment (User Equipment, UE) drop significantly, and the higher the number of pairing layers, the more significant the edge UE performance drops
